<div class="level3">

<p>
This function will check the day and the hour of current request, and compare it to allowed days and hours. It returns 1 if this match, 0 else.
All e
By default, the allowed days and hours is an hexadecimal value, representing each hour of the week. A day has 24 hours, and a week 7 days, so the value contains 168 bits, converted into 42 hexadecimal characters. Sunday is the first day.
</p>

<p>
For example, for a full access, excepted week-end:
</p>
<pre class="code">000000FFFFFFFFFFFFFFFFFFFFFFFFFFFFFF000000</pre>
<div class="notetip">The <a href="authldap.html#schema_extension" class="wikilink1" title="documentation:2.0:authldap">LDAP schema extension</a> can be used to store this value. You can also use the binary value from the logonHours attribute of Active Directory
</div>
<p>
Functions parameters:
</p>
<ul>
<li class="level1"><div class="li"> <strong>logon_hours</strong>: string representing allowed logon hours (GMT)</div>
</li>
<li class="level1"><div class="li"> <strong>syntax</strong> (optional): <code>hexadecimal</code> (default) or <code>octetstring</code></div>
</li>
<li class="level1"><div class="li"> <strong>time_correction</strong> (optional): hours to add or to subtract</div>
</li>
<li class="level1"><div class="li"> <strong>default_access</strong> (optional): what result to return if <strong>logon_hours</strong> is empty</div>
</li>
</ul>

<p>
Simple usage example:
</p>
<pre class="code">checkLogonHours($ssoLogonHours)</pre>

<p>
If you use the binary value (Active Directory), use this:
</p>
<pre class="code">All e
checkLogonHours($ssoLogonHours, &#039;octetstring&#039;)</pre>

<p>
You can also configure jetlag (if all of your users use the same timezone):
</p>
<pre class="code">checkLogonHours($ssoLogonHours, &#039;&#039;, &#039;+2&#039;)</pre>

<p>
If you manage different timezones, you have to take the jetlag into account in ssoLogonHours values, or use the $_timezone parameter. This parameter is set by the portal and use javascript to get the connected user timezone. It should works on every browser:
</p>
<pre class="code">checkLogonHours($ssoLogonHours, &#039;&#039;, $_timezone)</pre>

<p>
You can modify the default behavior for people without value in ssoLogonHours. Indeed, by default, users without logon hours values are rejected. You can allow these users instead of reject them:
</p>
<pre class="code">checkLogonHours($ssoLogonHours, &#039;&#039;, &#039;&#039;, &#039;1&#039;)</pre>
